Diablo Canyon reactor shut down after small leak

SAN LUIS OBISPO, Calif. (AP) -- A reactor at the Diablo Canyon nuclear power plant has been shut down so crews can perform repairs on equipment after a small leak was detected.

Pacific Gas & Electric Co. said the leak was discovered Wednesday in Unit 1 during routine maintenance, and that it was contained within the plant. The company said no radiation was released.

The company said the leak occurred in equipment that helps manage coolant used to control temperatures within the reactor, and that none of the liquid escaped into the environment.

PG&E did not know when the reactor would be brought back online.
